Fellow 21 Year old here, I'm glad you're following what brings you joy in life, and I am glad I am able to enjoy the fruits of that labor. I'm still in school, but I went through a heavy time similar to yours and threw myself into a project that helped me see that I was capable, much more so then I believed myself to be. I'm glad you see how capable you are, and that no matter what you do next, you'll have people who'll support you :).
